Description of the invention: [Technical field of invention] Local Ming system about earth pressure shield propulsion machine with sandstone temperature monitoring function and earth pressure latent red material preparation sand; 5 temperature monitoring Wei Zhitu pressure shield Even when the excavation object is used as a digging object and the excavation sand containing a large amount of printed stone and the like is placed in the chamber, the machine can also be used for the injection and the flow. (4) k (four) series of women's domain 11 riding rotation cut [previous technique] and monitored so as not to cause blockage. Roughly speaking, the earth pressure is soaked and smashed into the machine, and at the same time with the advancement: = the shield jack to push the shield to push the second one::: = = the cutter chamber (10) behind the rotary cutter The stone of excavation is filled with a rotating cutting screw machine. In the i and the self-cuttering chamber, the front side of the rotating cutter or the cutter chamber is injected into the excavation stone to convert the sandstone into a rich L-shaped crucible. Free deformation, the nature of movement) and play the impermeability of the soil. The soil is self-cutting - the thrust of the top, and the inside is full of the inside of the screw machine's and the water is pressed by the shield (hereinafter, called the soil) The earth pressure is generated against the earth pressure of the excavation surface and the ground pressure of the excavation surface. Hold the balance between the earth pressure and the ::::: intake and the amount of soil discharged by the screw machine to maintain the balance of 099145454 earth pressure, so that the surface of the excavation surface can be kept stable. However, there is a problem that a "clogging" occurs in the cutter chamber due to insufficient plastic flowability of the soil, and the rotation of the rotary cutter or the advancement of the shield jack is hindered by the clogging. , resulting in a situation that cannot be promoted for a while. In particular, when the site is spread with more boulders, such as boulders having a size of more than 0 500, and in addition to geological conditions such as pebbles or gravel, the excavation sand loaded into the cutter chamber will contain a large A lot of boulders or pebbles. These pebbles and the like are difficult to adhere to fine particles such as fine sand, and are therefore easily separated from the fine particles. Therefore, when discharging the screw to the screw machine from the chamber of the cutter, fine sand or the like can be smoothly discharged, and the boulders or large pebbles will remain in the cutter chamber and will not be sent to the snail. Therefore, it is considered that the retention of such large pebbles or the like may cause clogging. Patent Document 1 is known as a technique for preventing clogging. The "difference shield machine and chamber blockage management method" of Patent Document 1 is to monitor the fluidity of the sandstone in the chamber of the shield machine, thereby early detecting the blockage portion of the sandstone in the chamber, and the sandstone in the chamber. In order to solve the problem, in the shield machine, the gravel excavated by the cutting portion flows into the chamber from the gap of the cutting spoke, and is disposed in the hole below the partition wall by the screw machine. And discharged. A fluidity measuring device is disposed on the chamber side of the cutting spoke to measure the fluidity of the sand within the chamber. A plurality of earth pressure gauges and temperature are provided on the partition wall. 099145454 5 201224274 The earth pressure gauge measures the earth pressure change of the sandstone in the chamber. The thermometer measures the temperature of the sand in the chamber. In Patent Document 1, the frictional heat of the clogging sand and the stirring portion is generated in the sandstone clogging portion, and the heat from the cutter driving motor is not diffused to accumulate heat, so that it is compared with the surrounding sandstone. The temperature of the sandstone in the blockage of the gravel will rise. In other words, the control unit determines that the divided region of the sandstone temperature up to the lung constant value α is the high temperature portion and detects the position of the divided region as the position of the sandstone plugging portion. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei 8--232- No. Publication No. 8------------------------------------------------------------------ Stone blockage prevents people from happening. Under the critical condition of reaching the blockage of sand and gravel, the fluidity of the sandstone will be lost, so that the sandstone after the heat storage will stop at a fixed position, so that the blockage position can be found by measuring the temperature rise at the position. However, this stage can be considered to have almost reached the state of sandstone blockage. On the other hand, there is a problem that even in the stage of the smooth rotation of the rotary cutter from the flow state to the clogging, even if the temperature is increased due to friction, the stone can still flow in the chamber, so even if it is correct The temperature of the moving sandstone is measured #, and it is impossible to compare the position of the sandstone to the actual blockage of 099145454 6 201224274. That is, the plugging portion can be determined at the stage where the clogging is made and the sandstone cannot be moved, so that it is considered that the clogging cannot be prevented. Further, there is a problem in that the thermometer is placed on the partition wall where sand and sand are easily adhered. Therefore, if sand is adhered to a portion where the thermometer is provided, the temperature of the sandstone cannot be accurately measured. Further, when a digging sand containing a large and large amount of boulders or pebbles is loaded into the cutting chamber as described above, the dredging sand is pressed by the pebbles or the like in a state in which the rotary cutter is rotated. The portion of the void created by the withdrawal is believed to be generated throughout the chamber of the cutter, and since the portions of the gap move, disappear, or regenerate, even if a thermometer is placed on the partition to measure the temperature in the chamber of the cutter, It is considered that it is also difficult to properly determine the condition of the blockage. The invention is developed by the above-mentioned prior subject, and the object of the invention is to provide a soil pressure shield propulsion machine and a soil pressure shield method with a sandstone temperature monitoring function, even if the site with more gravel is used for excavation. Object, and the excavation sandstone I containing a large and large number of printed stones is carried in the cutter chamber! The moon rise can also accurately infer the movement condition of the cutter chamber rotating inside the rotary cutter' and monitor Make it not clogged. (Means for Solving the Problem) > The earth pressure shield propulsion machine having the sandstone temperature monitoring function of the present invention is subjected to excavation and pulverization by rotating from the excavation surface, and then the package is carried to the square by the screw conveyor. a cutter formed by dividing the partition wall behind the cutter

The specific configuration of the injection means 20, 22 and the injection means 21 for injecting the bubble material can be previously known. Further, in the present embodiment, the injection means 20, 22 for injecting the clay material and the injection means 21 for injecting the bubble material are separately disclosed, but the clay material and the bubble material may be used as the injection port ( It is not shown in the vicinity, or is mixed with the injection time of the mud material and the injection time of the bubble material, and is used as the injection means 20 and 22 for the mud material and the injection means 21 for the bubble material. That is, the clay material and the bubble material can be injected from all of the injection means 20 to 22. The sand containing the gravel portion of the excavation face Z which has just been excavated by the rotary cutter 2 is caused by the rotation of the rotary cutter 2 and the U-man means 2G from the rotation of the 099145454 12 201224274 cutter 2 The excavation surface 2 is injected into the cutter chamber 5 by the injection of the mud or the chaotic material into the (four) mixing and mixing.

In the earth pressure shield propulsion machine of the present embodiment, a sandstone temperature monitoring means is provided to monitor the blockage of the sandstone in the chamber 5. The tendency of the sand and gravel to be plugged is inferred by the increase in the temperature of the sand caused by the light heat of the sand and stone retained in the money. The sandstone temperature monitoring means is constituted by a temperature sensor 23 which is disposed inside the screw machine 8, preferably at the loading end of the screw machine 8 which is disposed close to the cutter chamber 5. The inside of the portion 8a, and directly measuring the temperature of the sand and gravel loaded by the screw machine 8 and loaded with the sand. A control panel 24 is connected to the temperature sensor 23, and the control panel 24 is disposed in the cab 1G and is used to display the sandstone temperature measured by the temperature sensor 23 to display the driver. Identify the temperature of the stone. Basically, by allowing the driver to recognize the sandstone temperature measured by the temperature sensor 23 via the control panel 24, the sandstone temperature monitoring function can be utilized, so that the driver can display the sandstone temperature according to the displayed In the present embodiment, the temperature sensor 23 is disposed in a screw machine 8 that uniformly and stably transfers the dredged sand, and is not disposed in the agitation flow to make the sand and gravel The position of the sandstone is stably measured by moving the position, or by causing a large portion of the gravel portion or the like to move, disappear, or reproduce the void portion. Moreover, the temperature sensor 23 is disposed at the loading end portion 8a of the screw machine 8, and the sandstone temperature of the excavating sand stone sequentially sent from the cutter chamber 5 to the screwing machine 8 can reflect the cutter chamber. The temperature data of the flow state of the sandstone in the 5th, and the measurement of the sandstone temperature riding time, and the position of the temperature sensor 23, because the screwing machine 8 system removes the excavating sand and the discharger There is less possibility of adhering the retained sand, so that the temperature of the sand can be accurately measured. The sandstone temperature detected by Lonely Sense/Stolen 23 is used for manual control by the driver. A control means 24a is placed on the control panel 24, and the hand oil is applied. [5 24 & sets the monitoring temperature for the occlusion estimation in the cutter chamber $ and makes the temperature of the material difficult to control the seam 24, and the driver manually outputs the injection means 2G to 22 to make the mud material. Increase the amount of increments in the L number. By using the clay material, the plastic flow of the sandstone in the cutting chamber can be improved. The yarn temperature detected by the degree sensor 23 can also be used to control the automatic (4) of the disk 24. The control (four) 24 system performs a step of comparing the monitored temperature with the measured sand temperature of 099145454 201224274, and via the comparison, when the sandstone temperature exceeds the monitoring temperature, the self-injection means operating portion 24a is performed on the injection means 20~ 22 The step of outputting the incremental signal to increase the amount of injection of the mud material. Regarding the monitoring temperature, depending on the state of the ground plate or the specifications of the shield propulsion machine, it is preferable to correct the temperature set in advance in each section based on the data obtained in the section of the initial stage of advancement.

Therefore, 'the soil pressure can be stabilized by using the mud material and the bubble material as a chemical agent', so that the excavation surface z red can be maintained, and at the same time, the soil of the screw machine 8 can be smoothed and prevented. Blockage occurs and it can also be prevented from being ejected. In this way, when the sandstone self-cutting chamber 5 containing the disc stone knife mixed with the mud material and the bubble material is loaded to the screw machine 8 for discharging, it is set in the screw machine 8 The internal temperature sensor 23 directly measures the temperature of the sand and gravel transferred in the screw machine 8, and the measured temperature is to be input into the control panel 24 for display. When the measured sandstone temperature is less than or equal to the H-degree, the sandstone is not blocked in the (4) chamber. It is possible to continue the pushing operation in the same driving operation as before. In other respects, the measured sandstone temperature exceeds the monitoring temperature and is the first! 099145454 201224274 When the temperature is below the threshold temperature, the plastic flowability of the sandstone will be lowered, and there is a tendency to block. Therefore, while the driving operation of the shield machine is continued, the injection means 2a is injected from the injection means operating portion 24a. 22, the incremental signal is output so that it can be incrementally injected into the excavation face z or the cutter chamber 5 from the injection means 20 to 22 as a mud material. The increment of the clay material continues until the sandstone temperature reaches below the monitored temperature. When the temperature of the sandstone is below the monitoring temperature, it can be inferred that the plastic flow is restored and the clogging tendency is eliminated, so that the output of the incremental signal can be ended, and the driving operation of the shield machine 1 can be continued in this state. Further, even if the above-mentioned operation is used to increase the amount of the mud material, if the measured sand/magnitude is still above the threshold temperature of the younger one, the plastic flow of the sand and gravel is insufficient, and there is a blockage portion. In the state in which the driving operation of the shield machine 1 is continued, the self-injection means operating portion 24a outputs the incremental signal of the injection amount of the mud material to the injection means 20 to 22 in increments of the injection amount of the mud material. Thereby, the injecting means 20 to 22 can be further incrementally injected into the mud material. The increment of the clay material continues until the sandstone temperature reaches below the monitored temperature. When the temperature of the sandstone reaches below the monitoring temperature, it can be inferred that the plasticity will be restored and the blockage will be eliminated, so that the output of the incremental signal is ended and the driving operation of the shield machine 1 is continued. At this time, the amount of injection can be reduced at a stage where the temperature of the sandstone reaches the temperature below the first threshold temperature. Further, the above description is performed while the driving of the shield machine 1 is continued, and the incremental injection of the mud material is performed, but the driving can be temporarily stopped and the incremental injection is performed. 5 099145454 19 201224274 In contrast to this, even if further incremental operation is performed, the temperature of the sandstone measured by the temperature sensor 23 tends to rise, and the driving operation of the shield machine 1 is interrupted and inspection and maintenance are performed. . The earth pressure shield propulsion machine 1 and the earth pressure shield method having the sandstone temperature monitoring function of the present embodiment set the temperature sensor 23 to be uniformly and stably transferred to the screw machine 8 for excavating sand and gravel, and It is not provided in the cutter chamber $ which is moved by the agitated flow to move the excavation sandstone or contains a large number of large shims, etc., so that the gap portion moves, disappears, or reoccurs, so that it can be stably Measure the temperature of the sand. Further, the / sensation state 23 is placed in the loading end 8a' of the screwing machine 8 near the cutter chamber 5, and the shovel = sand and gravel which is sequentially fed from the sump 5 to the screwing machine 8 The stone temperature reflects the temperature data of the flow state of the sand in the cutter chamber 5, so the temperature of the sand can be measured immediately. Further, the "spinner 8" transports the excavated sand and discharges it, so even if the temperature sensor 23 is placed inside the screw machine 8, the sigh position of the temperature sensor η is attached to the gravel. There are also fewer possibilities, so the temperature of the sand can be accurately measured. In addition, even if the excavation surface z of the site consisting of a sand butterfly or a stone layer of a sapphire stone that may be mixed with a boulders is used for excavation, the (4) & cavity to 5 (9) stone, etc. Compared with the case where the sand is generated by the excavation of the gravel, it is difficult to scale the sandstone temperature. Even in the case of the screw conveyor 8, even the gravel of the 3 disc stone part can be substantially uniform and stable 099145454 20 201224274 In the case of the ground transfer, the temperature sensor 23 can be installed in the screw machine 8 to measure the temperature of the sand and accurately estimate the flow condition in the cutter chamber 5, so even When excavating a site in which a large amount of such boulders X are scattered, it is possible to surely prevent the occurrence of clogging in the cutter chamber 5 or the like. Further, since the temperature of the sand measured by the temperature sensor 23 is input to the control panel 24 and displayed, the driver can appropriately perform the driving operation of the shield 1 . Further, the control panel 24 is provided with an injection means operating portion 24a' for setting the monitoring temperature and outputting the incremental signal for increasing the amount of the mud to the injection means 2?~22, so that the monitored temperature and the measured value can be measured. The correlation of the temperature of the fine stone makes the mud material increase, so that the blockage can be accurately prevented. Moreover, since the step of comparing the monitoring temperature with the sandstone temperature is performed in accordance with the automatic control corresponding to the control panel 24, and the step of increasing the thickness of the sand material is performed according to the degree that the sandstone temperature exceeds the monitoring temperature. Therefore, the anti-clogging control of the shield machine i can be automated. Of course, even if it is manually controlled, these steps can be performed to achieve an anti-clogging situation.
